LEVELING AIPARATUS FOR SPINDLES I1 1 EPENNING FRAMES.

Application filed. March 20, 1926. Serial no. 96,227.

This invention relates to a leveling apparatus for a spindle in aspinning frame.

I 3-3, Figure 2, and

The object of the invention is the construction of a simple andefficient apparatus for leveling or truing-up the spindle in a spinningframe.

VVi'h theforegoingand other objects in view, my invention comprisescertain novel constructions, combinations and arrangements of parts aswill be hereinafter" fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the'appended claims.

In the drawings: v Figure-'1 is a perspective view of my apparatus,showing the same on a spindle in a spinning frame, while V f Ihigure 2is a vertical, sectional view of the same. f

Figure 3 is a sectional view taken on line looking in the direction ofthe arrows. I

Figure 4 is a fragmentary sectional View of my apparatus shown on thetravelers ring. Figure 5 is a perspective view of'one of the two gagedevices, while Figure 6 is similar view of the said device, with theparts in different positions to thatshown in Figure 5.

Figure 7 is a view in elevation of the lower section of the frame of myaaparatus.

Referring to the drawings" 1 comprises the spinning frame, whichincludes the npperpart 2 and horizontal members 3 and 4. Mounted onthehorizontal member 3 is a spindle device 5 that includes a'baseportion 6 and a removable spindle 7 The spindle 7 is kept on the base 6by the weighted latch 8 (Fig. 1) this latch 8 has its .inner endprojecting into the slot 9 of the depending leg 10 of my apparatus, sothat while the spindle may be revolving, with my apparatus in positionthereon, yet'the apparatus will be held stationary.

On themember 4 of frame 1 is positioned thetravelefls ring 11, and thisring has a sleeve 12 that extends into a large opening 13 (Fig. 3) inmember 4, and by shifting the.

screws 14, either inwardly or outwardly of the supportmember 4, theposition of sleeve paratus upon the y numerals,

12can'be'bodily changed upon the support member 4. I 7

My apparatus includes a central sleeve or tubular like member 15 thatfits over the spindle 7 (Fig. 2) and'mounted on the lower end of sleeve2 is a casing16 that has a. ball bearing member 17 therein; this ballbearing member 17 fits snugly upon the spindle 7 and spaces" the sleeve15 and casing 16 from the spindle, so that the spindle can be revolvingvery'rapidly and yet the'sleeve 15 in casing '16 remainsstationarybecause to cas iug 16 is attached the leg 10 that has thelatch 8 extending into its slotted or bifurcated portion 9.

A; cross head 18 is'fastened on the upper end of sleeve 15, preferablyby screw 19 (Fig. 1), and a pair of rods 20 is mounted in the cross head18; each rod 20 of this pairhas its lower end extending into the crosshead 18, and by screws 21, these lower ends are fastened into place. Asecond cross head 22 is fastened on the upper end of rods 20, andmounted upon the top of cross head 22 is a disc 23. Slidably mountedupon the rods 20 is a cap casing 24. In this casing 24 is a rotatableball bearing follower 25. Theupper end of the spindle 7 engages and'eX-' tends into follower 25 ofcap casing 24, as shown in Figure 2.,This cap casing 24 helps to support the frame structure of my apspindle,with the spindle rapidly revolving, but by reason of the ball bearingmember 17 and ballbearing follower 25, no damage is done, for theseelements permit my leveling apparatus to perform its function dur ng therunning of the machine.

A pin 26 extendsat its upper end into an ordinary spirit level, withbubble 27 and pin 26 extends through cross head 22,with sleeve 28 andscrew 29 on its lower end for locking the level 27 upon the disc 23against displacement, although the level 27 is free to rotate upon thedisc. A pointer 30 is fastened to the top of level 27 preferably in itscenter, and this pointer 30, when the spindle 7 is registering true,will be right in the center of the eye element 31 that is attached tothe upper part of the frame, preferably by means of a hinged support 82.The thread from the ordinary spool or bobbin that is usually mountd onthe spindle 7 passes through the eye element 31.

It is to be noted that casing 24 is pro vided with side bifurcated lugs33 that straddle therods 20 whereby the casing is retained upon therods, but is allowed to slide vertically thereon.

To adjustmy apparatus accurately with in the travelers ring 11, Iprovide a ro-a tatably mounted bar 34, which is provided withbifurcatedends 35. Slidably mounted on the bifurcated ends 35 are gagedevices 36. Each device 36 comprises a lower section 37 and an uppersection 38. Theupper se'cti0n38 straddles the'bar 34, and the, lowersection 37 extends up .into the bifurcation 35, with the leg 39extending down and against the inner face of ring 11. The sections 37and 38 are held together by screw 40; By loosening screw or bolt 40, thegage device can be adjusted longitudinally of bar 34, whereby the gagedevices will fit any size ring 11, with their depending legs bearingagaginst the inner face of the ring, and permitting, when properlyadjusted, easy revolution of bar 34 and gage devices 36 upon the ring,whereby the operator will know that the apparatus is properly fittingthe The bubble 27 in level 27 showing when the spindle 'Z'is in perfectver tical positionand if the bubble 27 is not in the center of thelevel, with the legs 39 of the gage devices against the inner face ofthe ring 11, then the operator will know that he must slightly adjustscrews 14 to shift the ring 11, and then by placing any suitable wedges(not shown) under base 6 and on top of element 3, the spindle 7 can beshiftedslightly so that the bubble 27* will'be in the eXact center oflevel 27, whereupon the pointer '30 will register with the center of theeye element 31. lhen, as indicated hereinbefore, when the spool orbobbin is placed on the spindle 7, the thread or yarn therefrom willpass truly through the eye element 31.

When-the saindle 7 is re isterin )erfecta a. b ly, the travelers ringgaging means, constituted by bar 34 and gage devices 36, can be made torevolve freely on said ring; the level will have its bubble registeringin the center irrespective as to the rotary position of'the level on thedisc 23. It is important that the level 27 be rotatably mount ed? uponthe frame of my apparatus, so that it can be slowly rotated to determinewhether the bubble stands in the middle of the level, in the cycle ofmovement of the level upon the disc 23. and if the bubble does stand inthe middle, then the-operator who is using my testing and levelingapparatus on a spindle will know that the spindle is correctlypositioned upon the spinning frame,

From the foregoing description, it is to be understood that l. haveproduced a frame,

. means on said broadly speaking, that is adapted to be mounted upon aspindle, and on this frame is mounted a travelers ring gaging means, aswell as a rotatable spirit level. I have also provided means whereby theleveling means of my apparatus may be held stationary upon the rapidlyrotating spindle, with: out any injury occurring tomy apparatus.

While I havedescribed the preferred embodiment of my invention andillustrated the same in the accompanying drawings, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates during the eXtensive;Inanu-' facture of the same, andL therefore, reserve the riglit to make such changes or alterations asshall fairly fall within the scope of the appended claims.
